Application filed March 21, 1910. Serial No. 550,746.

To all whom it may concern:

Be it known that I, JosEPH CoRRoYER, a citizen of the United States,residing at the city of Oakland, in the county of Alameda and State ofCalifornia, have invented certain new and useful Improvements inAcetylene-Gas Generators, of which the following is a specification.

My invention relates to improvements in acetylene-generators.

The object of my invention is to provide a generator for the productionof gas from calcium carbid wherein danger is prevented, and a furtherobject is to provide such generator which combines strength, simplicityand ease of operation. I attain said objects by the mechanism shown inthe accompanying drawing and described in the following specificationsaid drawing showing parts of the apparatus in section to disclose theircontents.

Referring to the accompanying drawing numerals indicate parts of saidgenerator as follows, to wit 1 shows the shell of the apparatuspositioned outwardly which is secured by cleats 3 to bars 2. The bars 2support trans versely extending tubes 4 and.4 by means of tees 30 and 31and said tubes support by means of couplings 32 and 33 the verticaltubes 6 and 5 into which telescope the inner tubes 7 and 8 as shown. Theinner tube 7 is secured to and has an opening 12 into bell 9 and saidbell contains a basket 10 having a grating 14 supporting carbid 13 asshown. A side pipe 36 has a coupling 38 which is secured to the bell 9near its base and 0 ns into basket 10 as shown at 11. The pipe 36 has acoupling 39 secured to transversely extending pipe 37 which is securedto inner tube 8 by means of coupling 40. The cylinder 25 incloses theinner tubes 7 and 8 and contains water as shown to prevent the escape ofgas from said inner tubes. Hangers 34 and 35 are secured to tube 4 andsupport pulleys 23 and 23 on which is mounted the cord 22. The cord 22has one of its ends secured to the top of hell 9 and its other end tothe weight 24. Stop 18 is secured interiorly to the shell 1 wherebythe'bell and basket are prevented from descending lower than desired.Water chamber 1 is provided with an outlet pipe 20 having a valve 21 foropening the same, the said pipe being positioned at the base of saidshell so that the same may be cleaned.

The hook 15 is secured to the inner side of the basket 10 as shown at41, and has a short arm 16 which engages the projection 17 on the bell9. By pushing the hook 15 the same can be freed from such engagement soas to permit the bell to rise when the pressure of gas is upward, thebasket telescoping into the bell so as to enlarge the space for theaccumulation of gas when the apparatus is in action. The dotted lines 43show the position of the bell when the upward pressure of gas has forcedthe same upwardly to engagement with stop 19 which is adapted to turningto permit the disengagement of the basket and the bell. For theoperation of the apparatus the basket 10 is preferably filled withcarbid to the height shown in the drawing and water being poured intothe shell to the height preferably as shown the evolution of' gascommences. During the evolution of the gas the surplus gas rises throughthe aperture 11 and thence upward through pipes 36, 8 and 6 until it isdischarged through pipe 4 into the atmosphere. The illuminating gasrising from the carbid 13 ascends through pipe 7 into pipe 5 and thencethrough pipe 4 to a suitable outlet for the purpose of lighting. VVa-terjacket 25 is preferably filled with water to the height shown in thefigure so as to prevent the escape of gas from between the telescopingpipes. The heaviness of the weight 24 is adjusted so as to assist thebell to a gradual ascension as the upward pressure of the gas thereinincreases.

To charge the basket with carbid, the bell -9 is raised from itsposition as shown in the drawing until it clears the chamber 1; then thebasket is moved to one side and the same filled with carbid; then thebasket is restored to its proper position under the bell and the latteris lowered. The movement of the stop 18 and hook 15 permit the upwardmovement of the bell, and the couplings or tees 30 and 31 beingscrew-threaded permit the disengagement of the rods 2 and 2 therefrom,or the turning of the pipes 6 and 5 to one side after disengagement soas to permit the removal of the bell or its ascent as high as may bedesired. After the basket is filled v bination with capes upwardlythrough pipe 6 and thence through pipe 4 to the atmosphere at any pointto which pipe 4 may be carried, preventing the escape of tl twoseparable pper opening of pair of oppositely positioned pipes mountedabove said bell and telescoping over said said.

2. In an acetylene-gas generator the compipes leading as aforebinationwith a water chamber of a gas-bell g from said upper opening, a pair ofoppositely positioned pipes mounted above said bell and telescoping oversaid discharge pipes,

and a Water jacket mounted on said bell and surrounding said I adischargepipe leading from said upper o ening a pair of oppositelypositioned pi pes Inbunted above said bell and telescop- 111g over saiddischarge pipes, a water jacket 1 bell and surrounding said telescopingpipes, and a locking device having two separable parts, one of saidparts being connected to said basket and the other of said parts beingconnected to said bell.

In an acetylene-gas generator the combination with a water chamber of agas bell having an upper top opening and a lower side opening, a carbidreceptacle in said gas bell, a discharge pipe leading from said loweropening and extending above said bell, a discharge pipe leading fromsaid upper opening, a pair of oppositely positioned pipes mounted abovesaid bell and telescoping over said discharge pipes, a Water jacketmounted on said bell and surrounding said telescoping pipes, a lockingdevice having parts, one of said parts being connected to said basketand the other of said parts being connected to said bell, and a turnablestop for preventing the ascent of said bell beyond a determined point.

5. In an acetylenegas generator the co nmounted on said bination with awater chamber of a gas bell having an upper top opening and a lower sideopening, a carbid receptacle supported in said bell, a discharge pipeleading from said lower opening and extending above saidbell, adischarge pipe leading from said a pair of oppositely posiupper opening,tioned pipes mounted above said bell and telescoping over said dischargepipes, a water jacket mounted on said bell and sur rounding saidtelescoping said parts being connected to said basket and the other ofsaid parts being connected to said bell, a turnable stop for preventingthe ascent of said bell beyond a determined point, and means forassisting the ascent of said bell.

In testimony whereof I aflix my signature, in presence of two Witnesses.
